Thin films of CdS and CdSe and their use in alternative energy

The constant increase in energy consumption and rising prices for energy sources stimulate the search for new methods and materials for direct solar energy conversion. A critical analysis of scientific and technical literature shows that only thin-film solar cells (SC) can compete with traditional energy sources. Despite numerous studies on obtaining film coatings using various physical (vacuum deposition, sintering, screen printing, etc.) and chemical (electrochemical deposition, chemical bath deposition, pyrolysis, etc.) methods, the industrial implementation of film-based photovoltaic structures is hindered by the high cost of their production. In monograph the use of chemical surface deposition (CSD) to obtain CdS and CdSe films from aqueous solutions of cadmium-containing salts, will help solve the problem of reducing the cost of SC was described. The relevance of this direction is grounded in the fact that semiconductor photovoltaic structures based on CdS and CdSe films obtained by the CSD method fully meet the physical parameters required for application in thin-film SC.
